-Alanine -alaninium picrateAbstract: In the title compound, C3H7NO2·C3H8NO2+·C6H2N3O7-, each -alanine residue forms an asymmetric O-H
O hydrogen bond with its inversion-related partner [OO = 2.477 (4) and 2.472 (4) Å], involving disorder of carboxylic acid and carboxylate groups. The crystal structure is further stabilized by N-HO hydrogen bonds.
